Those advantages include low cost, lightweight, low signal loss, long life span, immune to EMI and RFI interference, and security from data leaks. They are also physically strong and well-suited to outdoor installations. Outdoor fiber optic cables are critical for building stable, high-speed networks in real-world environments. The next part will compare these fibers from the side of core size, bandwidth, data rate, distance, color and optical source in details. We covered them in detail in our Fiber Optics in the Future article.
